The condensation end evaporation reflux switch-on device 3 can be of a single structure, is internally provided with a conduction channel or more than two conduction channels, and can be respectively used as an evaporation working medium channel and a reflux working medium channel when more than two conduction channels are arranged. Of course, the condensation end evaporation reflux connection device 3 may also include at least two monomer structures, one of which serves as an evaporation working medium joint and the other of which serves as a reflux working medium joint.

In some embodiments, in which the condensation chamber member 1 is integrally extruded, i.e. by simultaneously extruding the outer shell and the inner ribs 11, an integrally formed connection is formed between the ribs 11 and the outer shell. Wherein the extrusion molding means that: the setting corresponds the extrusion die of cross sectional structure, let fluid or semifluid pass through this extrusion die in succession, and flow, and in the extrusion die in-process of flowing out through this extrusion die, solidify gradually, form along extrusion die export direction, along the extrusion direction promptly, the member of extension, concrete extrusion technology is like the forming means of present aluminium section, the forming means of cable sheath, what the forming of aluminium section adopted is an aluminium extrusion forming technology, consider heat conduction, cost scheduling problem, this condensation chamber spare 1 can be aluminium extrusion forming spare.

It should be noted that, the condensation chamber member 1 may be a flat plate member, a curved plate member, an annular member, or a cylindrical member, and the specific structure may be set as required. The condensing chamber member 1, if it is a plate structure, may comprise a plate-shaped shell portion forming an inner cavity therein and ribs 11 disposed in the inner cavity, wherein the ribs 11 in the inner cavity are connected to at least one inner shell wall of the plate-shaped shell, and generally, both side edges of the ribs 11 in the width direction are respectively connected to the two opposite inner shell walls of the plate-shaped shell, wherein the plate-shaped shell has a rectangular frame shape in cross section.

In some embodiments, because the condensation chamber member 1 is extruded, corresponding openings are formed at two ends of the condensation chamber member 1, and corresponding structures are required to seal the openings at the two ends. In particular, the condensation chamber element 1 can be closed at both ends in the extrusion direction by a closure element 2 and/or can be abutted against the condensation end vapor return connection device 3 for butt joint.

It should be noted that the function of the closure and the closure part 2 is to be understood in a broad sense: one is completely closed and the other is directed without an open setting. Wherein the drainage in the set direction: if the end openings among the plurality of condensation cavity pieces 1 are butted and the ends are in sealed connection, so that the fluid in the cavity of one condensation cavity piece 1 can flow to the cavity of another condensation cavity piece 1, the condensation cavity piece 1 can be regarded as a blocking piece 2 of another condensation cavity piece 1; as another example, the condensation end evaporation reflux switch-on device 3 also has the effect of setting the direction of flow, and therefore, the plugging member 2 should include all structures except the condensation end evaporation reflux switch-on device 3, which can perform flow in a specific direction.

Wherein the two ends of the condensation cavity member 1 along the extrusion forming direction are opened and closed by the plugging member 2 and/or attached with the condensation end evaporation reflux connection device 3 for butt joint, at least the following conditions can be included: both ends of the condensation cavity piece 1 along the extrusion forming direction are sealed by plugging pieces 2; the condensation cavity member 1 may be attached with the condensation end evaporation reflux connection device 3 at both ends along the extrusion forming direction for butt joint, specifically, the condensation cavity member 1 may be attached with different single structures of the condensation end evaporation reflux connection device 3 at both ends along the extrusion forming direction, or the condensation cavity member 1 may be attached with different condensation end evaporation reflux connection devices 3 at both ends along the extrusion forming direction; it is also possible that in both ends of the condensation chamber member 1 in the extrusion molding direction: one end of the condenser is closed by a plugging piece 2, and the other end of the condenser is attached to the condensation end evaporation reflux connection device 3 for butt joint; it is also possible that one end of the condensation chamber member 1 in the extrusion direction is open, one part is closed by a closing member 2, and the other part is abutted with the condensation end evaporation reflux connection device 3 for butt joint.

And because welding is not needed, the contact thermal resistance caused by cavity welding is successfully solved, and the appearance problem caused by welding is avoided.

In some embodiments, since the condensation cavity member 1 is integrally formed and only has one part, the problems of difficult assembly and high cost of the condensation cavity member are solved. And the yield of the product in the links of temperature impact, temperature circulation, high temperature, high humidity, aging and the like is greatly improved, so that the reliability of the product is greatly improved.

In some embodiments, the end of the rib 11 at least one end of the condensation chamber member 1 may be removed to form a vacant area 13 at the end of the condensation chamber member 1. The hollow space 13 can be used as an intercommunicating passage to intercommunicate the plurality of flow passages 12 at the end of the condensation chamber member 1, and certainly, the hollow space 13 can also be used as an insertion space of the blocking member 2, so that when the blocking member 2 is inserted and blocked, the plurality of flow passages 12 can be blocked at the same time, and the structure of the blocking member 2 is simple. The remaining space 13, of course, can also be slightly larger, so that in the direction of extrusion, the outer part is used for the insertion of the closure 2 and the inner part as the intercommunicating channel.

If the cooling chamber body is an extruded aluminum product, a milling cutter can be used for milling and removing the rib 11 part at the corresponding end of the cooling chamber body 1. The degree of removal is not particularly required, and may be set as required, for example, the end of the rib 11 along the extrusion molding direction may be completely removed, or a part may be removed to form the communicating passage.

It should be noted that, in the case where the end of the rib 11 at least at one end of the condensation chamber member 1 is removed, when there are a plurality of ribs 11, the end of each rib 11 at one end of the condensation chamber member 1 may be removed, the end of a part of the ribs 11 may be removed, and the specific configuration may be set as required.

The end of each rib 11, which may be at least one end of the condensation chamber element 1, is removed in its entirety so that the cross section of the remaining space 13 corresponds to the cross section of the shell interior.

In some embodiments, at least one of the blocking elements 2 may be inserted into the empty space 13 to facilitate installation of the blocking element 2, specifically, a strip-shaped blocking element 2 may be used, and the corresponding empty space 13 may be matched with the strip-shaped blocking element 2, in practice, in order to better shape the blocking element 2 for convenient manufacture and subsequent sealing connection, a part of the inner wall of the housing may be removed to enlarge the empty space 13 into the housing.
